Buss, owner of the Los Angeles Lakers (http://sportsillustrated.cnn.com/basketball/nba/teams/lakers), said in a rare interview that he has one regret regarding the shakeup of his team last summer: Shaquille O'Neal's angry reaction.

"I have not spoken to him," Buss said before Sunday night's game against the New Orleans Hornets (http://sportsillustrated.cnn.com/basketball/nba/teams/hornets). "I did call his agent and asked if we could have lunch before he left town. I plan on doing that again."

O'Neal has repeatedly expressed anger at the Lakers, general manager Mitch Kupchak and Kobe Bryant (http://sportsillustrated.cnn.com/basketball/nba/players/3118) since being traded to the Miami Heat (http://sportsillustrated.cnn.com/basketball/nba/teams/heat) in July.
